Abstract

The invention provides an anti-galloping device for a power transmission line. The device comprises a connecting rod, a grounding device and two spacers connected to the power transmission line, the two spacers are connected via the connecting rod, the first end of the grounding device is connected with the connecting rod, and the second end of the grounding device is connected to the ground. Compared with a manner that the spacers are hang in the air in the prior art, the two spacers connected with the connecting rod is connected to the ground via the grounding device, a downward pulling force is applied to the spacers to improve the stability of the spacers, the anti-galloping effect of the power transmission line is further enhanced, and the stability of the power transmission line is improved. In addition, the two spacers are integrated via the connecting rod to enhance the anti-galloping effect.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to an anti-galling device for transmission lines. Background technique [0002] In my country's power grid meteorological disasters, the ice-covered galloping of overhead conductors is a form of natural disasters with high frequency, wide range of influence, and large losses. With the rapid development of my country's power grid scale and the frequent occurrence of severe weather, since the beginning of the new century, the frequency of galloping accidents in the power grid has increased significantly, and the degree of harm has increased significantly. Large-scale galloping accidents have occurred almost every year, causing serious economic damage. loss and social impact. [0003] At present, spacers are mainly used to support the sub-conductors in the transmission lines of our country. When in use, the spacers are installed between the sub-conductors of the transmission line...
